Grid Monitoring Relay GMR100

INOTEL ELECTRIC

Grid Monitoring Relay GMR100

GMR series products of INOTEL brand are multifunctional network monitoring (Loss of Mains) relays positioned between the power grid and the power generation plant.

By continuously monitoring the city network, it separates the power plant and the power grid within milliseconds in case of any voltage or frequency disturbance that may occur and ensures that the power generation plant is restarted when the system returns to its nominal value.
